The Bosphorus Innovations Stage 2 RPM Water/Methanol Injection Kit delivers precise, engine-speed-dependent fluid delivery for high-performance builds. Utilizing an advanced digital RPM module, it triggers injection based on engine revs, providing a smooth, pulsation-free spray via an internal bypass pump architecture to lower intake temperatures and eliminate knock.
RPM-Based Activation: Automatically triggers water-methanol injection based on precise engine RPM thresholds for tailored power bands.
Pulsation-Free High-Pressure Pump: Standard 5+ bar pump utilizes an internal bypass mechanism (no pressure cut-off switch) to ensure an even, steady spray pattern supporting up to 1000 HP.
Digital Electronic Controller: Features live LED monitoring and user-adjustable activation levels.
Customizable Nozzle Selection: Pick from a wide range of nozzle sizes (95 cc to 2200 cc) to match your exact horsepower and fuel ratio needs. (Default: 252 ml/min [4 GPH] nozzle and Red Hose if unspecified).
Engineered for precision tuning, the Stage 2 RPM Water/Methanol Injection Kit links fluid delivery directly to your engine speed. By introducing a water-methanol mixture under specific RPM ranges, the system radically lowers intake manifold temperatures and exhaust gas temperatures (EGT)—protecting pistons from thermal stress while raising effective octane ratings to stop destructive engine knock.
Advanced Flow & Corrosion-Resistant Design Unlike basic systems, our high-pressure diaphragm pump uses an internal bypass configuration rather than a pulsation-prone pressure switch, guaranteeing a continuous, smooth flow. Every metal component is constructed from corrosion-resistant nickel-plated brass, standard brass, and EPDM-grade plastics certified for 100% methanol and water compatibility.
Key Benefits & Features
Combustion Efficiency: Increases dynamic compression, optimizes burn efficiency, and reduces harmful emissions (CO, CO2, NOx, and HC).
Complete Infrastructure: Includes a compact 3-liter HDPE plastic tank, digital controller, wiring loom, 6 meters of injection tubing, and a 40-micron stainless steel inline filter.
2-Year Warranty: Backed by Bosphorus Innovations’ comprehensive guarantee against manufacturing defects.
